So I tried the same reproducing script, mentioned in previous post, on linux-image 4.3.0-trunk-686-pae in experimental repo, and confirmed it cannot be reproduced, without applying my previous workaround. By a working workaround and fully fixed kernel in experimental repo, I suggest this issue can be closed. Thank you! Cheers, Roger
